Yukon Energy Corporation (YEC) (French: Société d’énergie du Yukon) is a Canadian Crown corporation in Yukon that provides electrical power to Yukon. YEC is a subsidiary of Yukon Development Corporation that was established in 1987 to take over the Yukon assets of the Northern Canada Power Commission. The company's headquarters is in Whitehorse, Yukon.
YEC generates virtually all of Yukon's electricity supply, and distributes power to a third of the locations outside of Whitehorse. Their largest customer (a wholesale buyer) is the Yukon Electrical Company (YECL), a private business that has been operating since 1901, which itself has some smaller hydro operations, and serves primarily the Whitehorse area plus two thirds of the rural communities. YEC itself provides customer electricity directly in Dawson City, Mayo, Faro, Champagne and to some isolated individual customers.
YEC has developed a grid that connects hydro facilities in Whitehorse (Schwatka Lake Dam - 40 MW from four wheels, the fourth added in 1983), Aishihik Lake - 30 MW, and the YECL facilities at Fish Lake near Whitehorse. The communities on the "Whitehorse-Aishihik-Faro" grid include Whitehorse, Champagne, Johnson's Crossing, Faro, and the following communities where it is distributed by YECL: Haines Junction, Carcross, Tagish, Marsh Lake, Teslin, Carmacks and Ross River.
